Installation

Radar is distributed as an npm package with two binaries:

• radar: CLI transport.
• radar-mcp: MCP server transport over stdio.

Requirements

• Node.js 20 or newer.
• A worker model API key.
• Network access to your chosen OpenAI-compatible provider.

Global Install

pnpm install -g @contextrail/radar

You can also use npm:

npm install -g @contextrail/radar

Project Install

For project-local use:

pnpm add -D @contextrail/radar

Then call the binaries through your package manager:

pnpm exec radar --help
pnpm exec radar-mcp

What Install Does Not Do

Install does not automatically add agent rules or MCP config to your project. Copy the examples from:

• AGENTS.md
• .cursor/rules/radar-delegation.mdc
• MCP Clients

This keeps Radar from mutating projects without an explicit setup step.
